REAR DISC CONVERSION

[beep_beep]

i am pritty sure this has been talked about many times, but i have a 89 CV and i want to change the rear to disc... but keep all the stock dimentions. so what would i need.

also while i have it apart i really would like to have posi-trac put in instead of always spining one tire in the rain cause it has alot of power... even if i LIGHTLY press the gas petal lol.

thanks

I would speak to either Lincolnmania or mrltd. They both have pretty much mastered converting the rear drums to discs.

I pulled the backing plates, calipers, and brake lines off a 94 Grand Marq. You have to pull the axels, after that you unbolt the drum backing plate and bolt the disc backing plate on. Then re-install the axels. There are two ways to do the brake lines. one is using you lines on the axels, or the frame mounted lines off the donor car. i used the frame mounted lines. i had to flare two lines and use a few flare fittings from the local hard ware store.

LIke he said.... you need rear disc backing plates and E-brake hardware, rear calipers, pads, rotors, caliper hoses, hard lines and new E-brake cables. the trickiest part of the entire swap is making the E-brake cables work.
Adding a limited slip carrier can be done, but can be complicated if you don't have the experience setting one up.

E-Brake. WTF is an E-brake?

you can butcher your own car how ever you choose, however mine is intact and working semi-properly.

I did not put it on because i dont really need one. the parking brake in my 97 that is mostly working, i have used it maybe once or twice in 2 years/30,000 miles. and even then i did not really need to use it.

If your brake's hydraulic system goes out, you may wish you had an e-brake.

In Eric's driveway, you NEED an E-brake...

I don't use mine either really, but they are nice to have... On Duce's nearly race-only el strippo vic, it is optional...

How much weight does the parking brake delete save, like 10 lbs? :evil:

not sure how much the parking brake on the rear disc weighs, but 10 pounds sounds about right. dont forget the heavy ass pedal assembly. i still need to remove that too.

10 pounds dont sound like a whole lot but 10 pounds here and there really adds up.

Guess people forget you will eventually be road racing the car...

I hope so.. but will most likely just be a well rounded car. not accel at anything but be good at several things.

I have deleted my parking brakes as well to save weight. I can usually find a big enough rock if I need to.

I haven't even done one yet... Still got all the parts sitting around. Lincolnmania is the guru...
